OPEN STOVE AND FIREPLACE.

Specification of Letters Patent.

same in both instances, both bengadapted to accommodate open fires.

In my invention I prov-1de a deflector or substantially horizontal guard at a point high above the bed or base, but with its entire top or upper surface at a level which is sufliciently below 'the top or mantel to producea horizontal inward draft high above the fire, but well below the top or mantel, the deiiector projecting far enough forward over the fire to prevent the cold air from falling and to force the hot air and smoke from the lire forward until it is caught by the horizontal draft of cold air and guided over the top of the deflector vand thence into the chimney-fine.

The principal object of the 'invention is to prevent the fire from smoking. v

The nature of the invention is fully described below and illustrated in the accompanying drawings, in which-- Figure l is a front elevation of a fireplace or stove embodying my invention. Fig. 2 is a central vertical section of the same. Fig. 3 is a similar section showing a modification Similar letters of reference indicate corresponding parts.

is the rear wall.

o is the top or mantel.

0l is an upwardly-extending flue which leads'v to the chimneyor which may be in the chim- 'The rear wall is deflected forward at e into the fireplace or stove over the lire until it constitutes the defiector g, said deflector bending rearward at L on a substantially horizontal line and the rear wall extending upward at 7c and constituting in connection with the front wall Z the walls of the upwardly-extending fiue d, which extends into and may be a part of the chimney. The entire length and width Lof the top /i of the deflector are at a level which is well below thev level of the shelf c.

In practice the cool air from the room approaches the horizontal passage above the deflector in a substantially horizontal line at a point high `above the lire and passes horizontally between the level of the shelf 0 and the top wall 7L and is then deiiected up into the flue d and into the chimney. As this draft of cool air enters the horizontal passage between the shelf c and the part /L it catches and carries with it the hot air and smoke from the lire which is at that point and has been carried forward by the deiector. Downdraft is prevented, so that the cold air cannot drop to the fire, and thus smoking of the fire is obviated.

In Fig. 3 the deflector is not an integral portion of the rear wall, but consists of a separate piece s, secured toV said rear wall in the same position and approximately in the same shape as the deflector g and with substantially the same eect.

Having thus fully described my invention, I

what I claim, and desire to secure by Letters Patent, is-

In an open stove or fireplace, the forwardlyextending horizontal top or mantel c; the vertical wall Z extending up from the mantel, and the rear vertical wall h, whereby a vertical flue d is produced between said walls; andthe deliector consisting of the substantially horizontal top wall L located below the mantel, and the forwardly-extending wall e, whereby a horizontal passage or. flue is produced next and below the mantel, said passage or liue occupying the entire space between the wall /L of the deector and the mantel, and connecting directly with the said vertical iiue, substantially as set forth.

In testimony whereof I have signed my nam to this specication in the presence of two subscribing witnesses.
